Spoken language dialogue systems (SLDSs): high-complexity
multi-task, task-oriented spontaneous speech systems, particularly
dialogue management and human factors development; next-generation
conversational domain-oriented SLDSs which are no longer defined in
terms of the tasks they solve but solely in terms of their knowledge
domains; extension of SLDSs to natural interactive systems including
facial expression, gesture, and bodily posture input/output; Modality
Theory and multimodal systems; virtual meeting spaces; wearable
devices and ambient intelligence; best development and evaluation
practice for SLDSs and natural interactive systems more generally;
natural interactivity corpus development and analysis: data, coding
schemes and coding tools; ITC research strategy and brainstorming. I
